Various phthalonitrile-based resins were prepared and their copper clad laminates were fabricated in this work. The curing behaviors and mechanisms were investigated by Dynamic rheological analysis (DRA) and in-situ FTIR. Results indicated that all phthalonitrile-based resins possessed wide process temperature windows and exhibit good processability. https://www.rivervalleydanceac.com/product-category/dolls/
